SAVE TIGERThe tiger is a unique animal which plays a pivotal role in the health and diversity of an

ecosystem. The zoological name of tiger (national animal) is Panthera Tigris. It is a carnivorous

animal which comes under the category of mammal as it gives birth to a child. It belongs to the

cat family as a largest living member. It is found all around Asia especially in the countries like

Bhutan, China, India, and Siberia. Tiger is an endangered species-(species that are in danger of

becoming extinct in the near future.)Due to decline in their number of the animal- however few

are left (according to the world tiger census) all over the world which we have to conserve in any

way in order to save their life on the earth.

It is estimated that almost half of the total population of tigers are living in India. However, in

the last few decades, the population of tiger in India was decreasing to an extent. There are six

living subspecies of tigers found (such as Bengal tiger, Siberian tiger, Sumatran tiger, Malayan

tiger, Indo-Chinese tiger, and South-Chinese tiger) and three have been recently extinct (such as

Javan tiger, Caspian tiger, and Bali tiger).

The extinction of this top predator is an indication that its ecosystem is not sufficiently protected,

and neither would it exist for long .If the tigers go extinct, the entire system would collapse. The

Project Tiger was launched by the government of India in 1973 in order to protect the existence

of this royal animal in the country.

It is the matter of happiness that because of the Project Tiger campaign, the population of tigers

in India is in a comfortable position.
